Changing my Apple Account Primary email Address

Refer to this support article: Change your Apple Account primary email address - Apple Support

“You can change your iCloud email address using a device with iOS 18.1 or later, and iPadOS 18.1 or later.” I don't see a way to do this on a Mac. If you do not have the required equipment, consider using email aliases instead: Add and manage email aliases for iCloud Mail on iCloud.com - Apple Support

Those @me addresses are a nuisance from what I have seen from other posts here. I am not sure if even Apple can help you with those (from what other posts have said) but you are welcome to ask them.

Select from the presented options until you find a solution for your issue, or see if there is a chat or phone call contact method offered lower on the page (you sometimes have to narrow down the options multiple times before this is shown). If you do not see your issue, keep experimenting with any series of selections until you reach one that offers a chat session or a telephone call and get the representative to redirect you.

This support article has various country telephone numbers for contacting Apple for support and service ➔ Contact Apple for support and service - Apple Support For some countries look under “Other” listing at the end of each region. Not every country has telephone support.
